Objective
Temporary or permanent implants (orthopedic, cardiovascular, dental, contraception implants, devices for fracture stabilization, etc) are widely used in medicine. However, after implantation the biomaterial-associated complications like allergological and foreign body reactions, problematic tissue regeneration, and infections often lead to revision surgery.
The aim of the proposed project is to develop a new surface coating (biocoating) for implants which allows eliminating/minimizing these complications. T he biocoating represents the multi-layered polyelectrolyte film with incorporated drug-loaded liposomes. The liposomes have a role of reservoirs with biologically active drugs ¿ drugs, which support healing of wound (implantation is done by surgery) or/and antibiotics to prevent bacteria colonization. The use of stimuli-sensitive liposomes or stimuli-sensitive polyelectrolyte film gives opportunity to control liposomes integrity and as a result to control a release of the drug loaded in the liposomes.
The main advantages of the biocoating are:
a). Drug release may be controlled by ultrasound as external stimulus, which is non-invasive treatment, well focused, and comfortable for a patient;
b). Local application of drugs released from biocoating directly to surrounding tissue is advantageous in that high local levels without systemic toxicity can be achieved.
The constituents of the film (lipids and polyelectrolytes) are chosen to be biocompatible. The biocoating allows enhancing biocompatibility of implant surf ace using polyelectrolytes promoting specific interaction with proteins and cells.
